I figured spending the extra money on a US made product would at least get me working products. I only got half. My TDS meter freezes at random times and takes forever to unfreeze. When I put it in different cups of water that I know have different hardnesses, it doesn't budge. It just stays the same. The strips that came with this kit worked and were easy to read, but the TDS meter is a piece of junk that needs immediate repair. To make matters worse, there is nothing in the guide to troubleshoot, nor is there a number to call. If there was a way to call the manufacturer I wouldn't do it.
